In the meantime, I’ve seen people doing these nowadays (in the marine field) without films. I did a search and found a product by Trolase, but it doesnt come in large enough pieces. Know any other options with a black on back, clear on front, that allow you to engrave the black away to allow light to penetrate?

Can you double it up? Use a 1/4” thick 2 color, then put a 1/4” clear piece on top? I’m not sure of what adhesives are available for acrylic, but it may be an option? Or if they could be mounted stacked without adhesive between the layers it might be viable too?

Edit: maybe do the spray paint and then sandwich the painted side with another layer of clear? Might holdup better?

I thought about adding the clear to the back. I’m just worried that having the two pieces sandwiched, if not ‘adhered’ to each other, they would gradually shift back and forth and scuff the paint. I’ll experiment a bit.

Off topic - but just ordered the Carbide 3 XXL!

Now, what bits would I start with for this type of carving? And where should I look to purchase them for a beginner (assuming there will be mistakes).
